This invention relates to desk sets of the vide a mounting which permits a'wide range 1 15 of adjustment and which isnot restrictedto said predetermined adjusted positions; to

provide a mounting which is simple in construction, easy and economical to manufacture, and neat in appearance while being dur- 9 able and serviceable; and in general,- it is the object of my invention to provide an im-- proved mounting of the class described.

Other objects and advantages of my invention will be understood by reference to the 2 following specification and accompanying drawings in which Ihave illustrated a desk set including a base and a pen receiving socket 1 adjustably secured to the base by means of a mounting embodying a selected form of my invention. s

In the drawings: Fig. 1 is an end elevation of the desk set; Fig. 2 is a fragmentary sectional view on an enlarged scale, the section being taken on 35 a plane extending through the axis of the socket and parallel with the end elevation of Fig. 1; t

Fig. 3 is a section on the line 3-3 of Fig. 2, and s I I Figs. 4; and 5 are perspectives of certain elements of my improved mounting.

Fig. 6 is a diagram illustrating the arrangement of the pivotal connection between the pen socket and base, the dimensions in this 45 view being exaggerated to facilitate illus-' tration.

such as shown in Figure 1 includes amain base of suitable material, such as metal,

50 marble, wood, or of composite construction,

and a pensocketfl which is desirably mounted on the base 5 so that the socket can be adjusted, in both horizontal and vertical planes, so that the socket will project the pen in the general direction of a person desiring to use the same. A pen seated in the socket .6 is indicated at 7.

For adjustably mounting the socket as above described, I provide a swivel mounting which includes abase member or ferrule 8having an internally threaded sleeve part 9 fitting in an opening 10 provided in the main base 5. The ferrule 8 includes the flaring head portionll which serves to position the .ferrule'on the top .12- of the base, and a screw 13 fitting the internally threaded sleeve part 9 serves to prevent upward displacement of the ferrule. The ferrule is preferably :clamped tightly in place by tightening the screw 13 so that the ferrule is fixed and cannot rotate relative to the base.

A stem or post 14 is rotatably mounted in the ferrule 8, the post being provided with an enlarged head portion 15 which serves to provide a shoulder 16 for engaging a shoulder 17 provided in the ferrule, thereby to prevent upward displacement of the post. The upper portion 18 of the post 14 is preferably flattened in cross section, as shown in I Figures 2 and 3, and provided with an opening19for receiving a pivot pin 20.

A hub member 21, preferably cylindrical in form as indicated in Figures 2 and 5, is pivotally mounted on the pivot pin 20, the said hub memberbeing provided with an aperture 22 for receiving the pivot pin, and a slot 23 for receivingthe flattened post portion 18. It will be seen that the hub member 21straddles the flattenedpost portion 18 and is pivotally mounted thereon so that the hub is adjustable about a horizontal axis. A sleeve element 24 is disposed around the 'hub 21, the said sleeve being provided with a slot 25 for, receiving the flattened post portion 18, and the said sleeve and hub are inter- I locked by (means of a screw 26 which passes through an aperture 27 in the sleeve and threadedly engages an internally threaded hole 28 in the hub. The screw26 also serves to securethe socket membercto the hub and sleeve, as clearly shown in Figures 2 and 3. The sleeve 24 is of larger internal diameter than the external diameter of the hub, and by means of the connecting screw 2611s caused a to assume an eccentric position with respect to the hub. It will thus be apparent that the distance tromthe axisofethe-pivotpin 20 to-the'bottom portion 29Jof-the sleeve is diii'erent than the distance from tl elax is of m the said pivot pin to the top or sides of the sleeve, and that the sleeve will-be caused to frictionally engage the top surfaceBOQoftlle ferrule 8. If desired, the aperture'22 in the 29 increased. 7

:As shown in: Figures L3,:the parts are arranged so that the huh'QLand sleeve 24k are in :contactatitheir upper portions and so maintained' by the screw 26. :iThe-zeccentric --re-lation between the. hnbcan d sleeve-and .:the I dimension-betweenthe pivot-axislandithetop 530mm madeilto :be suchrthat the. sleeve -will havethe desired vfrictional engagement with the top 1300f the 'ferrule'i'lor holdingcthe socket l in adjusted :position. :It ravill-benotedmthat the :engagementi between; the sleeve=and fer- -rule:serves to frictionall'v; hold theasocketf 6 in vertically.adjustedlposition, i. e.,-;a-bout:the aXis-of thenpivot 20, @IldigfilSOHiIIEh-Ql'l zonta llyadjustedposition, i.;e.-,,about the-axis of the post 14-.

However, as a practical matter the increased radius jlength andits normalleffectjon the-,fri'ctional rwmar ibe weensaid sleevean'drtop surface,

is compensated "i'c'or'by reason of the greaterease with which the sleeve yields or flexes as a whole to either side of the short radius 35 when the socket is swung towards its horizontal position, as compared with the stiller resistance to yielding or flexing on both sides of the sleeve as required when the socket is in or near its vertical position. i

in short, the variation in resistance of the sleet e to yielding or flexing compensates for the variation in the eli'ective radius of the -sleeveand-a substantially uniform tension is wobtainedior holding the, socket in adjusted position'tliroughout the range of its adjustment 7 j V.
